The Gulf of Guinea Giant Land Snail (búzio-d'Obô)
The islands of São Tomé and Príncipe host a unique species of giant land snail (Archachatina bicarinata). This species was abundant and well recognized by locals, having a special cultural importance.
However, it has suffered a rapid decline in the last century due to a combination of habitat destruction, introduction of exotic species and intense harvesting. The species can be currently found exclusively in the most remoted areas of the native forest on both islands.
The São Tomé giant land snail is rapidly disappearing and in need of serious conservation measures.
With this project we aim to raise awareness among local populations and tourists of the São Tomé’s islands about the species, the impacts and consequences of human activities on natural resources, using it as a flag species to promote nature conservation.
Project funded by:
The Gulf of Guinea Giant Land Snail can reach above 16 cm and its eggs can be as big as olives.
It is an herbivorous and litter decomposer, associated to well-preserved forests.
The giant snail is important for locals as a food and medicinal resource. In the past shells were also used to protect houses from spells.
